C型胞质雄性不育系塘四平头,经过多年异地不同气象条件鉴定,不育性遗传稳定,一般环境条件的变化不影响雄性表现。获白恢复系经过测定,不同来源的姊妹系之间恢复性能不同。同一来源的获白恢复系不同单株之间恢复性差异很大,有全恢复、半恢复、不恢复三种。通过单株测交、自交、选择可以选出全恢复系和保持系。全恢复系和部分恢复系在不同环境条件作用下,恢复性受到明显影响,部分恢复系比全恢复系更为显著。利用C型胞质不育系配制杂交种优于原同型杂交种。
C-type cytoplasmic male sterile line Tong Siping, after many years of different weather conditions identified, genetic stability of infertility, the general changes in environmental conditions does not affect the male performance. White restorer line has been measured, different sources of sister between different recovery performance. Restoration of the same source of white restorer different between different strains vary greatly, with full recovery, semi-recovery, not recovery of three. Through single plant test, selfing, selection can be selected to restore the Department and maintain Department. Under the different environmental conditions, the recovery of all restorers and some restorers were significantly affected, and some of the restorers were more significant than the restorative restorers. The use of C-type cytoplasmic male sterile line hybrids is better than the original homotype hybrids.
